On Windows, you type in a fairly long command to get it, instead of just “ethtool “, which is shorter. You’re comparing the graphical tools available on Windows to the command line of Linux. Apples and oranges.

Tried this on ubuntu, uhm, 8 or something (was some old usb livestick i often use to revive data from dead computers and laptops). I had to install the ethtool first, but a permission denied. This command worked though: sudo apt-get install ethtool Then I tried the first command in this article, which gave me no info and I didn´t know howto get out of the program. Closed the terminal and opened it up again, then ran the second command. Permission denied. But a sudo !! did the trick. In short, this would work after doing the apt-get-install: sudo ethtool eth0 | grep -i speed

apt-get and ethtool are administrator tools hence the need to use sudo before the actual commands. Users are normally not able to use them as they can affect the system and possibly cause major failures in connectivty or software.
